Not Quite Running Circles Around Dad

In a wonderful story going nowhere — actually just round and round &jmdash; Graham Rahal will race in the Indianapolis 500 for his father's Rahal Letterman Racing. The older Rahal, Bobby, claimed the Indy championship in 1986. The son's previous two years at Indy have resulted in 31st and 33rd place finishes. However, he wasn't racing for his pop (or co-owner Dave Letterman, who has yet to announce his racing intentions for son Harry Joseph, age 7). Anyone (except perhaps pops) think third time's the charm?
